Four people were killed Wednesday after a small plane crashed on a highway in Riverdale, Utah.

All four occupants of a single-engine Beechcraft Bonanza were killed when the plane crashed into the northbound lanes of I-15 around 1 p.m., burst into flames and came to a rest in the median, authorities said.

Police said there was a gap in the traffic on the highway when the plane crashed, so no one on the ground was hurt.
